Ever been in a hotel with other people who stay up a little later than you? Its not like its that much later, but enough, but you don't wanna look like a loser and ask them to fall asleep? So you suck it up, stay up an hour later, and feel tired as hell the next day, and of course you say it'll never happen again, even though it's the next day, same two roommates, tired as hell and ruminating on the whole thing.
